SB 600 vs Metz 50 AF-1

OK, another question for the gurus. I am planning on getting a flash for either the D7000 or D300s (whichever I decide on). I currently have a Metz 48 AF-1 for Olympus, and really like it -- the build quality, power, recharge rate, etc are all fantastic. I am debating between the newer version of this one (the 50 AF-1) and the Nikon SB 600. The 900, while looking nice, is out of my price range.

For those familiar with both models, what (if anything) would I be missing if I went with the Metz? It supports CLS as a slave (just like the SB 600), is more powerful (if I am reading the gain specs properly), and recharges very fast. I am currently leaning towards the Metz, but thought I would see if there is anything obvious which I am missing from the equation.
